NUMERICAL MODELLING OF NOMEX HONEYCOMB CORES FOR DETAILED ...

Key Words: Nomex honeycomb, virtual testing, meso-scale, explicit FEA Abstract. Detailed numerical analyses of honeycomb sandwich cores, where the core cell wall geometry is modelled accurately (meso-scale), have found increasing applications in the recent past. However, such simulations require additional material properties as well as model validation. Based on a literature review, the ...
